IMPROVEMENT IN THRASHING-MACHINES.

Specification forming part of Letters Patent No. 42,921, dated May 3l, 1864.

To all whom it may concern:

Be it known that I, PELEG BAKKER, of Battle Greek, in the county of Calhoun and State of Michigan, have invented anew and useful Improvement in Machines for Thrashing and Separating Grain, Src. and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and letters of reference marked thereon.

This invention relates to a certain improvement, substantially, to any well-known grain thrashing and separating machine, as the Pitts7 machine.

The accompanying drawing is a perspective view, exhibiting the several parts-viz., eccentric shakers A A A, angular beaters B B B, hinge-shore D, and vibrating spout C. The eccentric shakers A A A are attached to an extended frame, Q Q, by means of shafts F FO F, resting in bearings in opposite sides of extended frame Q Q. Near the opposite ends of shafts F FO F are firmly att-ached arms E E E. Said arms are so constructed as to admit of rod S S S to connect them parallel with shafts F F O F. The said shafts have cranks of equal length attached to their extreme ends, and all are connected by a pitman.

The motive power is applied by means of belt and pulley T. Said pulley is firmly attached to the een ter shafts, F O. The cranks and pitman are not shown in the drawing, they being on the opposite side of extended frame Q Q. Said extended frame is so attached to the machine as to form a continuation of the strawcarrier frame and to admit of the passage of straw, 85e., onto the eccentric shakers A A A, for the purpose of more thoroughly liberating the unthrashed heads of grain, Src., from the straw.

The angular beaters B B B are firmly attached to shaft 6 in such position as to vibrate the straw, 85e., in its passage. Said angular beaters are constructed and placed at reversed angles around shaft 6. The cover 0 is raised to more clearly show the mechanism of angular beatersB B B, as can be clearly seen in the drawing. The shaft 6 rests in bearings in the sides of the straw-carrier fra me, as can be seen at 5 5. The hinge-shore D is attached to the lower and the hind part ofthe frame at W by means of a hinge or its equivalent. The lower part of said shore is notched for the purpose of raising and lowering the` hind end of the machine with more ease, to raise the machine while operating is for the purpose of filling bags with grain, &c., and returning unthrashed heads of grain, &c., by means ofvibrating spout @,without the employment of elevators 5 and to lower the hind end of the machine to facilitate its transportation from place to place, the vibrating spout C is attached to a crank on the Aopposite end of shaft (i, and also rests on an inclined plane at 8, and extending along the opposite side of the machine from the feed-mouth 9 to a point at the hind end of the machine, where it receives the unthrashed heads and scattered grain, &c.

I will describe the operation of my machine as follows: When the operator wishes to thrash grain, tvc., he raises the hind end of the machine from its position marked by dotted lines 7 7 T, and liberatcs the notched end of the hinge-shore D from its rest at U. lt then describes the curve shown by dot-ted lines L L, until it comes in contact with the bolster or rest, where he can raise it to the required height by means of the notched end as seen at the numeral el.

The feeding of the machine being generally understood, I will proceed to describe the operation ot' the angular beaters B B B. They are operated by means of a belt and pulley, as seen at l0. Said pulley is firmly attached to shaft 6, as seen in the drawing. The angular beaters B B B revolve with shaft 6, when they come in contact with the straw and grain, 85e., vibrating it from right to left, and to the contrary, as it comes in contact with the reversed angles ofthe angular beaters B B B, thereby spreadingthe straw, 85e., uniform on the strawcarrier, and facilitate the separation of the straw and grain. The chaff and straw pass over the straw-carrier and fall upon the eccentric shakers A A A, which lift the straw with an upward and onward motion by means of the rods S S S, the said rods describing in uniformity the upper and lower arc of the circle, consequently leaving the straw to rest on the shafts F FO F, while the rods S S S de- :cribe the lower semicircle, and when said rods describe the upper semicircle they force the straw over the end of extended frame Q, therebyleaving'the unthrashed heads of grain, Sac., free to fall through the bottom of extended frame Q into vibrating spout C, said spout forcing the nnthrashed heads of grain, 85e., back into the feed-mouth of the machine 9 by means of the compound motion given to the vibrating spout C by means of the crank on the end of shaft 6 and inclined plane at 8. Then, to place the machine in its former position, the operator raises the notched end of the hingeshore D from the bolster or rest, the notched end of said shore describing the circle marked by the dotted lines L L back to its former position at U, then lowering the hind end of the machine back toits position described by dotted lines marked? 7 7.

After describing my machine, what I claim, and desire to secure by Letters Patent, is

l. The hin ge-shore D, or its equivalent, for

raising the machine for the purpose of discharging grain, Src., into bags or returning unthrashed heads of grain, 85e, by means of Vibrating spout C, Without the use of elevators, as herein specified.

2. The eccentric shakers A A A, for the purpose of more thoroughly separating the unthrashed heads of grain, 85e., from the straw, as herein set forth.

3. The angular beaters B B B, they being adjusted by reversed angles around sha-ft 6,for the purpose herein described.

PELEG BAKKER.
